ohh... okay thanks so much! i really appreciate it. it makes sense now. ;)

Math
correction* 3 meters is too less room.

Math
Okay. That's true, 3 meters is a pretty wide space. I figured out the first dimension, it's 29.8 m. I still need the second dimension so I can figure out the area of the fenced space.

Math
A tennis court is 23.8 m by 11 m. A tennis club has 3 courts side by side in a fenced area. The courts have 3 m between them and 3 m around the outside. What are the dimensions of the fenced space? Please and thank you!
